• αʹ Vitruvius, De Architectura 10.2.6:

Ita funis ductarius traicitur in inferioris trocleae foramen, uti aequalia duo capita sint funis, cum erit extensus, ibique secundum inferiorem trocleam resticula circumdata et contenta utraeque partes funis continentur, ut neque in dextram neque in sinistram partem possint prodire.

So the tow rope is fed through an opening in the lower block, so that both ends of the rope are even when it is stretched out, and then both parts are held along the lower block by a cord wrapped around and tied so that they can't come out, either on the right side or the left.
